To all whom it may concern:

Be it known that I, WALTER J. BEL L,'a citizen of the United States, residing at Los ngeles, in the county of Los Angeles and State of California, have invented a new and Power-Applyin Apparatus for Oper- Switches, Signai, and other Devices,

lowing is a specification.

signals, and other devices 11 this invention the space between the air valve and the cylinder, Or other device through which the power of the compressed air is applied, is reduced to a minimum.

is invention embraces liquid means for the control of the pneumatic means; to say, I have provided in this power apparatus li uid meansby which the pneumatic The comprise apparatus air or by suction or means may also be der pressure or suction.

the The means for causin the liquid means an h pneumatic means may be of any ll-known kind. In the application of this invention for the ration of switches or signals, a lever may be rovided for operating the li uid means, and said lever may be actauted manually, magnetically, or otherwise, as may be deemed eslrable or expedient. A princi le of this invention is that a valve for contro ing the pneumatic means by admitting air from the supply pipe to the engine from which the power s. applied, is located close to such engine, and in turn is operated point or for other service, may

. mechanism.

bodying this invention in with the top removed. Fig. 3 is a side elevation of such chest. Fig. 4 is a fragmental, sectional elevation illustratin the application of the invention as applie for operating a switch close by.

he pneumatic means comprises in a general Way, air supply and exhaust pipes 1, 2; a poWer-appl ing device or engine 3; air supply and ex aust pipes 4, 5; valve means 6 or controlling the passage of the air for ower-appl device 3. The or control ing the pneumatic way, comprises supply respectively; pneudevice or engine 9 by piston rod 10 to operating the iquid means means, in a general and exhaust pipes 7, 8,

mane-valve controlling y connected as suitabl operate the pneumatic'valve means; pressure and exhaust pipes 11 and 12 for a plying pressure to operate the pneumatic-valve controlling device; valve means 13 for controlling the passage of the pressure, medium 14 for 0 erating the pneumatic-valve controlling evice 9, and means 15for operating the valve which controls the passage of the pres.- sure medium.

16 designates a pressure or exhaust'pump for the pneumatic means, and 17 a pressure or exhaust pump for the liquid means. 18 and 19 are receivers or tanks for said pumps, respectively.

20 is the cylinder of the pneumatic powerapplying device or engine 3; 21 'is the piston,

and 22 the piston rod therefor, ports 23, 24,

being in said cylinder, one on each side of the piston, each of said ports being both for supply and exhaust.

25 is a valve chest provided with air supply and exhaust ports 26, 27 and connected with pipes 4 and 5.

28 designates valves in the valve chestfor controlling the air for said .orts said valves are reversely arranged. he valve chest 25 is composed of two chambers 29 and 30.

31 is a way communicating between the chambers 29 and 30, and connected with the pressure pipe 1. 32 is a waybetween said chambers and'communicating with the exhaust pipe 2.

33 is an internal valve for simultaneously opening the way into one chamber and closing that into the other chamber, andlvice versa.

34 is an external valve for simultaneously opening the passage between way 32 and one o amber, and closi the passage between said way and the ot er chamber, and vice versa. 35 is 'a beam pivotally connected with said valves for operating the same, and also pivotally connected with the piston rod 10 w ereby the beam is operated for working the valves. The valves are provided with guides a. for holding them true.

36 is a cylinder, and 37 'a piston therein for operating the rod 10', ports 38, 39, being provided communicating withthe pipes 11 and 12, respectively, and being on oppositesides of thepiston 37.' p

40 is a valve chest having ports '41, 42, for pressure and exhaust.

43 indicates valves in the valve chest for controlling the pressure medium 14 and reversing its movement through pipes 11 and 12. Said valve chest has two chambers 44, 45, and ways 46, 47, between said chambers communicating through ports 41 and 42 withpressure and exhaust pipes 7 8.

48 is an internal valve for simultaneously closin the pass e between the way 46 and one 0 said cham ers, and 0 ,ening. the passage between said way and t e other ofsaid chambers, and vice versa. 49 is an external ,valves 33 and 48 taken out.

, connecting rod connecting said beam with an arm 54 of rock shaft 55 controlled by lever 56.

The internal valves 33 and 48 are located within their respective ways and comprise two heads 5, c, which engage internal valve seats (1, e according as the valve may be shifted. The external valves 34 and 49, respectively, comprise two heads,-f, g, arranged outside the ways 32 and 47 respectively, and

seating on external seats h, 2', respectively, in every case a valve seat being placed on each side of the way ports 26, 27, 41 and 42.

57, 57, are caps for the valve chests.

58, 58, are ca s for the Ways 31, 46, between the cham ers,.59, 59 are plugs to give access to :the exterior valves 34 and 49, res ectively.

or disassembling and assembling the Valve means for repair or otherwise, the caps 57, 57, may be removed, thus giving access to the valve chambers 29 and 44 whereupon the caps 58, 58, may be removed and the To take out the external valves 34 and 49 it is necessary to remove the plugs 59, 59 whereupon the valve heads g may be unscrewed from the valve rods, 52, after which the external valves may be removed from their ways.

In practical operation, pressure or exhaust will be effected so that the ressure medium 14 will be forced from the i et 7 toward outlet 8, and like pressure or exhaust will be exerted to force the pressure medium in the pneumatic means from the inlet 1 toward the outlet 2.

To operate the power-applying engine or device 3 the lever56 will be moved manually or otherwise in an appropriate direction for closing the inlet passage 46 into one chamber, as 44, and opening said passage into the other chamber, as 45, and'at the same time closing the exhaust passage 47 .from chamber opening the exhaust ,assage 47 from the chamber 44,.whereupon t e pressure mepassing from the cylinder 36 throu h pi e 1 1 and out through passage 47 an ex aust pipe 8. By th1s operation power is trans- .mitted through the incompressible li uid .dium willoperate through the pipe 12 to force piston 37 up, said-pressure medium passa e, whereupon the pressure medium will ow through pipe 5 to move the iston 21, the pressure medium in the cylin er 20 being expelled through pipe 4, passage 32 and exhaust pi e 2.

In the form s own in Fig. 4, 60 is a handle for operating a pump piston 61 which applies power through iqu1d medium 62 to operate the diaphragm 63 and through the rod 64, beam 65 to operate valves 57, 68, of the pneumatic means 6", whereupon the pressure medium operates as before described upon the power-applying device or engine to move the switch or other device to be operated.

It is to be understood from Fig. 4 that I contem late using a diaphragm as the equivalent o a piston, and that the invention may be variousl embodied without departing from the spirit thereof.

It is to be understood that in case of pneumatic means it is only necessary to connect either the su ply or the exhaust with the pressure or tile vacuum pump, as the case may be. In the drawings, however, a comlete connection or circuit for the fluid meium is shown. Such parts of the same may be omitted as the constructor may find it desirable to dispensewith.
